多个predicates

use NSCompoundPredicate for your multiple predicates, you can refer NSCompoundPredicate Class Reference

Use NSPredicate to search multiple fields

NSPredicate endswith multiple files

NSStringEnumerationOptions	说明
NSStringEnumerationByLines	按行
NSStringEnumerationByParagraphs	段落
NSStringEnumerationByComposedCharacterSequences	字符顺序
NSStringEnumerationByWords	单词，字
NSStringEnumerationBySentences	句子
NSStringEnumerationReverse	反向遍历
NSStringEnumerationSubstringNotRequired	不需要子字符串
NSStringEnumerationLocalized

-(void)processEditing
{
    NSRange paragaphRange = [self.string paragraphRangeForRange:self.editedRange];
    NSArray *extensions = [NSArray arrayWithObjects:@"strong", @"copy", @"assign", @"nonatomic", nil];
    NSPredicate *predicateWords =[NSPredicate predicateWithFormat:@"SELF IN %@", extensions];
    // 创建谓词对象并设定条件的表达式
    //    NSPredicate *predicateNS = [NSPredicate predicateWithFormat:@"SELF MATCHES '%@'",kATPattern];
    NSPredicate *predicateWD = [NSCompoundPredicate orPredicateWithSubpredicates:@[predicateWords]];

    [self.string enumerateSubstringsInRange:paragaphRange options:NSStringEnumerationByWords usingBlock:^(NSString * _Nullable substring, NSRange substringRange, NSRange enclosingRange, BOOL * _Nonnull stop) {
        NSLog(@"substring=%@",substring);
        if ([predicateWD evaluateWithObject:substring]){
            [self setAttributes:@{NSForegroundColorAttributeName:[NSColor redColor]} range:substringRange]; //当出现关键词如strong单词时字体变红
        }
    }];
}

多个匹配命令

// 按顺序获得所有（包括不匹配）字段的 range 数组以重新拼接
NSString *regex = [NSString stringWithFormat:@"%@|%@|%@|%@|%@|%@",kUserPattern, kCopyPattern, kNonatomicPattern, kNSClassPattern,kStrongPattern,kAssignPattern];
NSRegularExpression *expression = [NSRegularExpression regularExpressionWithPattern:regex options:NSRegularExpressionCaseInsensitive error:nil];
[expression enumerateMatchesInString:self.string options:0 range:paragaphRange usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) {
    // Add red highlight color
    [self addAttribute:NSForegroundColorAttributeName value:RGB(194, 53, 154) range:result.range];
}];
